项目摘要

The broader impact/commercial potential of this I-Corps project is to explore the opportunities of using a new technology to help manufacturers make carbon fiber composite products with higher production speed and lower cost. This novel fabrication technology produces materials that are stronger, stiffer, thinner, lighter, and better conductors of heat and electricity than current carbon fiber composites widely used in manufacturing industries. Parts produced from these new materials are more accurately made and have less internal stress remaining after manufacturing than previously. In addition, this technology will also reduce the energy consumption and material waste during the operation of vehicles and equipment that utilize them. Since carbon fiber composites are being increasingly used in many industries including aerospace, automotive, energy, marine, sporting goods, and defense, successful commercialization of the new technology catalyzed by this I-Corps project will bring significant benefits to the U.S. manufacturing base.This I-Corps project is based on a new technology using long ultra-thin carbon nanofibers to thread through a bed of conventional thicker carbon fibers all surrounded by an epoxy resin adhesive. As a result, the thicker fibers are strongly bound together by the nanofibers, and all are held in place by the epoxy, to produce a composite material that is much stronger than either the epoxy resin alone or the conventional carbon fiber composite including the epoxy. This is called "z-threading". The network of interlocked carbon nanofibers and carbon fibers significantly improves the composite material's strength and conduction of heat and electricity. Conventional carbon fiber composite materials, typically in the form of a laminate, lack the z-threading nanofibers and have significantly poorer properties across the thickness direction of the laminate. As a result, manufacturing processes currently using carbon fiber composites will be significantly improved. This will allow production of more aggressively designed components with higher performance than has been possible before.

这个I-Corps项目更广泛的影响/商业潜力是探索使用新技术的机会，帮助制造商以更高的生产速度和更低的成本制造碳纤维复合材料产品。这种新的制造技术生产的材料比目前广泛用于制造业的碳纤维复合材料更坚固，更坚硬，更薄，更轻，更好地传导热和电。用这些新材料生产的零件制造得更精确，制造后残留的内应力比以前更少。此外，该技术还将减少使用它们的车辆和设备在运行过程中的能源消耗和材料浪费。由于碳纤维复合材料越来越多地用于包括航空航天、汽车、能源、船舶、体育用品和国防在内的许多行业，由I-Corps项目推动的新技术的成功商业化将为美国的制造业基地带来巨大的利益。细碳纳米纤维穿过全部由环氧树脂粘合剂包围的常规较厚碳纤维床。因此，较厚的纤维通过纳米纤维牢固地结合在一起，并且全部通过环氧树脂保持在适当位置，以产生比单独的环氧树脂或包括环氧树脂的常规碳纤维复合材料强得多的复合材料。这被称为“Z线程”。互锁的碳纳米纤维和碳纤维的网络显着提高了复合材料的强度和热传导和电传导。常规的碳纤维复合材料，通常为层压材料的形式，缺乏z-穿线纳米纤维，并且在层压材料的厚度方向上具有明显较差的性能。因此，目前使用碳纤维复合材料的制造工艺将得到显著改善。这将允许生产具有比以前更高性能的更积极设计的组件。
